Abstract: Properties, structural features, and basic principles for the synthesis of some new carbon-carbonaceous composite materials (CCM) originating at the Boreskov Institute of Catalysis are discussed. The CCM are synthesized via chemical growth of carbon deposits in a pre-formed porous carbon matrix. Among the CCM are: Sibunit produced by supporting pyrocarbon (PC) on carbon black granules, carbon filaments (CFC) produced by decomposition of CH<subscript>4</subscript> over Ni or Ni−Cu catalysts, CFC on Sibunit, CFC on ultradispersed diamond, and systems such as CFC/CFC, PC/CFC, etc. Basic mechanisms of structure and texture formation of CCM and some of their properties as adsorbents and catalyst supports are reported.
